I've run 3 staking methods over all the 82 posted selections.
1) Flat £20 stake = profit of £ 92.20
2) Comparible Fixed return = £ 107.70
3) Rolling 5% percentile of 1000 point bank = £ 87.64
Whereas your rolling treble/quad has doubled even these returns
I'm just trying to get my head around an equation to run similar through excel.
